24 39 To all' 'wlihnt may eoacern Be it known that I, DoR'snf1P, IL Q Qa i n of the United States, resident of Venus, county of VenangO, andState/ Qff Pennsylvania, have invented anew and use-V ful Improvement inSteering Mechanism for Wheels, of whichtthe following is a specfication, the principle of the inventionbeing. herein explained and thebest modem which .I have contemplated applying that The object of myinvention is-to provide] tached to the axle of the: vehicle in a mannersuch as to promote safety 1111188 and facility-of,operation, especiallyas regards the steering of the vehicle.

The said invention v hereinafter. fully described and particularly setforth in the claims. a 3

The annexed-drawing and the following description set forthin detailcertaiumeans embodying my invention, the disclosed means, however,constituting but one of van rious mechanical forms in which theprinciple of the invention may be employed.

In said annexed drawing: Figure 1 represents a vertical transversesection. of a fragmentary portion'of my improved steering mechanismtaken upon a plane passing through the wheelaxis;

Fig. 2 represents a transverse axials'ecj tion of a fragmentaryrportion'of themechanism, taken upon the plane indicated by the line II'II, inFig. 1. i

Figs. 3, 4, 5 and 6, represent,respectively, a plan view, an elevationfrom one side, an elevation from a diametrically opposite side, and atransverse vertical section in the plane indicated by the v line VVIVI,Fig. 5, of'a tertiary journal member, hereinafter more fully described.7 I Figs. .7, 8, 9 and 10 represent, respectively,

an elevation of one face, a side elevation, an elevation of the otherface,

and a plan view of a secondary journal member, hereinafter more fullydescribed. I The inner part of my improved wheel comprises a primaryjournal-member 1 which is formed with an outer peripheral raceway 2 forreceiving the anti-friction roller bearings 3. This primaryjournalmember furthermore is constructed of two p the member 1, as shownin consists of means transverse square hole 15 .or shoulderof. the saidaxle.

I, i is furthermore provided forexcluding dust from the adjacent surfaces of the bearing 10 and member13, as will be readily understood.

The member 1 is furthermore provided with an integral and laterallyextending steering arm 25, Fig. 2. Assuming the primary journal-member land its attached parts to have been removed from the wheel, the partsthus far described are dismounted as follows:

The dust cap is firstunscrewed, whereby access to the nut'19 isobtained. The cotter pin having been removed and the nut removed fromthe portion 17 of the axle, it will be seen that the latter may bewithdrawn from the secondary and tertiary journal-members. By nowunscrewing the nuts 7 and removing the bolts 6, the parts t and 5 maybeseparated, after which the secondary journal-member '11 may be pushedthrough the hole 1 1 and then removed. This leaves the tertiaryjournal-member 1 3 free to be slipped'ollthe axle.
